User profile service not updating 'Title' in user information list

Hi,

In our SharePoint farm, following two user profile sync timer jobs are successfully running but not updating the 'Title' in the hidden user information list.

User Profile to SharePoint Full Synchronization

User Profile to SharePoint Quick Synchronization.

Can someone point me to the right direction? Please note that I don't want to use powershell script shown here to update the 'Title' in the user information list - http://blog.falchionconsulting.com/index.php/2011/12/updating-sharepoint-2010-user-information/.

Thanks,
